In the rental and repair of generators, it is often necessary to clean the oil, carbon, scale and rust on the surface of parts. Due to the different nature of various pollutants, their eradication methods are also different. So what are the ways to clean the parts of the generator?

一、油污清洗 零件外表的油污沉積較厚時(shí)應(yīng)先刮除。二手發(fā)電機(jī)出租清洗零件辦法，一般清洗零件外表油污，常用的清洗液有堿性清洗液和合成洗滌劑。運(yùn)用堿性清洗液進(jìn)行熱清洗時(shí)，加熱至70~90℃，將零件浸入10~15min，然后取出并用清水沖洗潔凈，再用壓縮空氣吹干。

1、 When the oil deposit on the surface of oil cleaning parts is thick, it shall be scraped off first. The method of renting used generators to clean parts is generally to clean the oil on the surface of parts. The commonly used cleaning fluids include alkaline cleaning fluid and synthetic detergent. When using alkaline cleaning solution for thermal cleaning, heat it to 70 ~ 90 ℃, immerse the parts for 10 ~ 15min, then take them out and wash them with clean water, and then blow them dry with compressed air.

二、積炭鏟除 鏟除積炭可運(yùn)用簡(jiǎn)略的機(jī)械鏟除法。即用金屬刷子或刮刀等進(jìn)行鏟除，但此辦法不易將積炭鏟除潔凈，而且易損傷零件外表。選用化學(xué)辦法鏟除積炭，即先運(yùn)用退炭劑（化學(xué)溶液）加熱至80~90℃，將零件上的積炭脹大，然后再用毛刷等進(jìn)行鏟除。

2、 Carbon deposition can be removed by simple mechanical removal method. That is, remove it with a metal brush or scraper, but this method is not easy to remove the carbon deposit, and it is easy to damage the appearance of the parts. Chemical methods are used to eliminate carbon deposits, that is, first heat the carbon remover (chemical solution) to 80 ~ 90 ℃, swell the carbon deposits on the parts, and then remove them with a brush.

三、水垢的鏟除 發(fā)電機(jī)清洗一般選用化學(xué)鏟除法，將鏟除水垢的化學(xué)溶液加入到冷卻液中，發(fā)動(dòng)機(jī)作業(yè)必定時(shí)間后，再更換冷卻液。常用鏟除水垢的化學(xué)溶液有：苛性鈉溶液或鹽酸溶液、氟化鈉鹽酸除垢劑和磷酸除垢劑，磷酸除垢劑適合用于鏟除鋁合金零件上的水垢。

3、 The chemical removal method is generally used for cleaning the generator. The chemical solution for removing the scale is added to the coolant. The coolant can be replaced after the engine operates for a certain time. Common chemical solutions for scale removal include caustic soda solution or hydrochloric acid solution, sodium fluoride hydrochloric acid scale remover and phosphoric acid scale remover. Phosphoric acid scale remover is suitable for scale removal on aluminum alloy parts.
